摘要

本文研究了非金融企业在风险管理活动中使用金融期权的动机和实践。为此,它提供了一个全面的现有经验证据的使用衍生品和期权,特别是非金融公司在不同的基础和国家。总体而言,15%-25%的金融部门以外的公司使用金融期权。这反映了一个事实,即期权是非常通用的风险管理工具,可以用来对冲各种类型的风险,无论是线性的还是非线性的。特别是,如果风险暴露是不确定的,例如由于价格和数量风险,期权是公司风险管理的一个有用组成部分。根据价格和数量风险之间的相关性,最优对冲投资组合由线性和非线性风险管理工具的不同组合组成。此外,会计处理和流动性效应也会影响衍生工具的选择。与此同时,可能存在与机构相关的动机促使投资者使用期权,因为它们的作用是对标的未来的走势和波动性进行双重押注。

The Use of Options in Corporate Risk Management
This paper investigates the motivations and practice of nonfinancial firms with regard to using financial options in their risk management activities. To this end, it provides a comprehensive account of the existing empirical evidence on the use of derivatives in general and options in particular by nonfinancial corporations across different underlyings and countries. Overall, a significant number of 15%-25% of the firms outside the financial sector use financial options. This reflects the fact that options are very versatile risk management instruments that can be used to hedge various types of exposures, linear as well as nonlinear. In particular, options are a useful component of corporate risk management if exposures are uncertain, e.g. due to price and quantity risk. Depending on the correlation between price and quantity risk, the optimal hedge portfolio consists of a varying combination of linear and nonlinear risk management instruments. Moreover, the accounting treatment as well as liquidity effects can impact the choice of derivative instrument. At the same time, there may be agency-related incentives to use options because of their role to present dual bets on both direction as well as future volatility of the underlying.
